HOSE CONNECTION.

Specification of Letters-Patent.

Application filed June 12, 1908.

Patented July 6, 1909.

Serial No. 438,147.

To all whom it may concern:

Be it known that I', IRA S. DUNMYER, a citizen of the United States 'of America, residing at Grafton, lin 4the county of Allegheny and State of Penns lvania, have invented certain new and use l Improvements in Hose Connections, of which 4the following is a specication, reference being had therein to the accompanying drawing.

This invention relates to automatic valves for hose couplings ol gas pipes, and the primary object of my invention is to provide a novel valve for automatically shutting off a supply of gas should the hose become accidentally disengaged from the ends of gas pipes.

Another object of this invention is to provide valves that will be opened when the ends of a hose are slipped upon the ends of gas mnpcs.

Alim-ther ob'ect of this invention is to provide a simp e durable and inexpensive automatic valve that can be used in connection with the present t pe of hose connection. FJith the above an other objects in view which will more readily appear as the invention is better understood, the same consists in the novel construction, combinationV and arrangement of parts to bev hereinafter described and then specifically pointed out in the appended claims.

ln t 1e drawings, Figure 1 is a longitudinal sectional view of a gas pipe valve casing or coupling and hose connection equipped with my automatic valves, the hoseconnection being partly broken away. Fig. 2 is a longitudinal sectional view of one of the automatic valves in a closed position, Fig. 3 is a sidev elevation of the same, Fig. 4 is a side elevation of a detached valve and valve stem, Fig. 5 is a longitudinal sectional view .of another automatic valve forming a part of my invention, and Fig. 6 is a side elevation oi? the same.

' ln the accompanying drawings 1 desig natos a gas su (ply pipe `valve casing or couplingprovide with a valve 2 of a well imown form, said valve being manipulated by hand to shut otl the supply of gas.

"inthe endthegas supply pipe'l. is located an automatica-valve comprlsmg a cylindrical `or tubular body 3 having-the inner end` thereof formed with a valve seat el having openings 5, to permit of gas passing from the valve casing 1 into the valve body in the valve body 3 is slidably mounted a Vthis application there is illustrate spider bearing 6 havin a valve stem 7, said stern extending centra ly through the valve" seat 4 and longitudinally of the valve body- 3. One end ofthe stem 7 is n'ovided with a valve 8 and the opposite end thereof with a pivoted latch 9; said latch being of a greater ength than the diameter of the valve bod 3, one end of said latch will protrude throng a slot 10 provided in the valve body 3.

Interposed between the s ider bearing 6 and the valve seat is a coi spring 11, said spring encircling the stem 7 and normally tending to close the valve 8 and place the latch 9 in the upright osition shown in Fig. 2 of the drawings. 7hen the end 12 of a hose is placed upon the protruding end of a i valve body 3, the latch 9 is forced inwardly and at an inclination, thereby opening the valve 8 and placing the spring 11 under tension. Should the end 12 of the hose become accidentally disengaged from the valve body 3, the coil sprin 11 would immediately close the valve 8 an prevent gas fromI escaping. The automatic valve used in connection with the op osite end 13 of a hose comprises a cylindrica body 14 located in the hose adjacent' to the end thereof, sufficient space being allowed at the end of the hose, whereby the same can be mounted upon the gas outlet pipe 15. The c lindrical valve body 14. is also formed witi a valve scat 16, through which passes a valve stem 1.7 carrying a valve 18, a head 19, and an intermediate spider bearing 20. interposed between the spider bearing 2Q and the valve seat- 16 is a coil spring 21. The head 19 is normally held against the gas )ipe 15 by the coil spring 21, and should the liose 13 become accidentally disengaged from `the pipe 15, the release of the head 19 allows the spring 21 to close the valve 13, consequently, gas cannot escape from the end 13 of the hose.

lt is apparent from thenovel construction of my automatic valves that positive and reliable means is employed for preventing the esca e of gas from a gas supply pipe, should either end of a hose connection be detached, consequently, my invention pre-- vents waste of gas and danger of asphyxietionb the sam y Wh1le in the drawings forming a part of d t e preferrd embodiments of my invention, I would have it understood .that the elements therein canv be varied or changed, asto sha e, proportion and exact manner of assemblage,

without departing from the spirit of the in- Vention.

Having now described Iny invention what l claim as new, is gl. The combination with a coupling, of a tubular body mounted in Vthe outlet end thereof and projecting beyond said coupling and having a slot in said projecting )ortion7 the inner end of said body provided with a valve seatJ a spider slidabl-y mounted in said body7 a valve stein carried by said spider and. projecting on opposite sides thereofI a Valve Carried on the inner end oi said stem., a latch pivoted to the outer end ot said stern, with one end 'irojeeting through the slot in said tubular oody, and a spring between the Valve Seat and spider for seating the said Valve when the latch is released.

2. The eoinbination with a coupling, of a tubliler body mounted in the outlet end thereof and provided intermediate its ends @weee at a point outside the coupling with a slot and having a Valve seat at its inner end, a hose section having one end sleeved on said tubular body, a spider slidably mounted in said tubular body, a valve stemearried thereby and projecting on opposite sides of the spider, a valve on the inner end of said stein, a latehseoured to the outer end of said stern having one end thereof projeetiigf. through the slotsin said body and engaged by said hose section -lor normally holding said Valve out of engagement with said Valve seat, and means for automatically seating the Valve when the hose-*section is disengaged 35 from the tubular body. i

ln testimony whereof I affix my signature in the presence oi t'wo Witnesses.
